Removal and replacement procedures 26
WARNING: To reduce the risk of personal injury, electric shock, or damage to the equipment,
remove the power cord to remove power from the server. The front panel Power On/Standby
button does not completely shut off system power. Portions of the power supply and some internal

2. Press the Power On/Standby button to place the server in standby mode. When the server enters
standby power mode, the system power LED changes to amber.
